NameRWeostream - Rogue Wave library class
Synopsis
#include <rw/estream.h>
// Construct an RWeostream that uses cout's streambuf,
// and writes out values in little-endian format:
RWeostream estr(cout, RWeostream::LittleEndian);
Description
Class RWeostream specializes the base class RWbostream to store values in
a portable binary format. The results can be restored via its
counterpart, RWeistream. See the entry for RWeistream for a general
description of the endian stream classes.
Persistence
None.
Example
See RWeistream for an example of how the file "data.dat" might be read.
Enumeration
enum RWeostream::Endian { LittleEndian,
BigEndian,
HostEndian }
Used to specify the format that RWeostreams should use to represent
numeric values in the stream. HostEndian means to use the native format
of the current environment.
Public Constructors
RWeostream(streambuf* s, Endian fmt = HostEndian);
Construct an RWeostream from the streambuf s. Values placed into the
stream will have an endian format given by fmt. For DOS, the streambuf
must have been created in binary mode. Throw exception RWStreamErr if
streambuf s is not empty.
RWeostream(ostream& str, Endian fmt = HostEndian);
Construct an RWeostream from the streambuf associated with the output
stream str. Values placed into the stream will have an endian format
given by fmt. For DOS, the str must have been opened in binary mode.

Throw exception RWStreamErr if streambuf s is not empty.
Public Destructor
virtual ~RWvostream();
This virtual destructor allows specializing classes to deallocate any
resources that they may have allocated.
Public Member Functions
virtual RWvostream&
flush();
Send the contents of the stream buffer to output immediately.
virtual RWvostream&
operator<<(const char* s);
Redefined from class RWbostream. Store the character string starting at
s to the output stream. The character string is expected to be null
terminated. Note that the elements of s are treated as characters, not
as numbers.
virtual RWvostream&
operator<<(char c);
Redefined from class RWbostream. Store the char c to the output stream.
Note that c is treated as a character, not a number.
virtual RWvostream&
operator<<(wchar_t wc);
Redefined from class RWbostream. Store the wchar_t wc to the output
stream in binary, using the appropriate endian representation.
virtual RWvostream&
operator<<(unsigned char c);
Redefined from class RWbostream. Store the unsigned char c to the output
